Alternative to ChIP. MaGellin can also be used to screen the binding specificity of transcription factors (TF) and other DNA binding domains, with methylation serving as an effective reporter for targeted binding.
By fusing a TF to the methyltransferase, its binding with the plasmid becomes easily detected by the associated methylation
In this situation, one would vary the “target site” to see which DNA sequences have the strongest binding to the TF
This technique would be significantly faster, simpler, and cheaper than a ChIP-based method
